Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525888, here are decompositions:

17 + 525871 = 525888
19 + 525869 = 525888
71 + 525817 = 525888
79 + 525809 = 525888
107 + 525781 = 525888
149 + 525739 = 525888
157 + 525731 = 525888
179 + 525709 = 525888

Showing the first eight; more decompositions exist.
